Question

Before noon on Tuesday, there was a certain number of hex nuts in a bin. After a delivery at noon that day, the number of hex nuts in the bin increased by 30%. Which of the following could be the number of hex nuts in the bin after that delivery?

Answer 1

The number of hex nuts in the bin after that delivery are 1.3x.

Explanation:

Let the number of nuts in the bin before delivery be = x

After a delivery at noon that day, the number of hex nuts in the bin increased by 30%.

Means x + (30% of x)

This gives :
`x+0.3x=1.3x`

Hence, the number of hex nuts in the bin after that delivery are 1.3x.
